Have only had my copy a little over a week myself so I haven't played with it too much. I haven't had your problem though. Initially I had a "shaky" problem but somehow got around that (not sure how, just a bit of luck). Now I seem to get it to work ok, I just played with the same clip for a day trying a bunch of different settings...mostly I get a softer image but the scene is very steady.
Guess I'll have to play with it a bit more and try a few more different thing's. Have you tried the 2d3 FAQ's page?
Sorry I couldn't help any further.
